Hi, everyone

I'm using COAWST as my coupled model by activating the ROMS and WRF models. To save the calculation cost, I wish to run a two-domain WRF and one-domain ROMS.
The parent domain of WRF has the same grid as ROMS. If I don't have a two-way nested domain in the WRF, I actually do not need to activate the MCT_INTERP_OC2ACT option.

However, I am not sure whether I should use scrip_coawst to generate the weights when I want to run a two-domain WRF.

I didn't find any examples, but I did find a paper saying that they coupled ROMS only with the second WRF domain.
That paper's title is 'Impact of Coupling an Ocean Model to WRF Nor’easter Simulations' (Nicholls and Decker 2015).

Many thanks if you can give me some suggestions.

Best regards,

Ning Zhao, Ph.D.

When COAWST runs it will look to see that you have 2 WRF grids selected and then it will try to get data from both wrf grids to roms. So i suggest you do the weights. You can try it without the weights but i dont think it will work.
